Why do I need crawlspace ventilation?
The presence of moisture is what leads to mold, which can be bad for your health and costly to remove. According to the Environmental Protection Agency, the way to control mold is to control moisture. The main source of crawl space moisture is ground evaporation, and ventilation allows this evaporation to dissipate. Proper ventilation exhausts moisture from the crawl space and replaces it with fresh, drier air - providing effective moisture control. Ventilation also helps to remove strong odors and dangerous radon gas from the crawlspace.
What is a portable exhaust fan system?
The Portable Exhaust Fan System converts our Portable Fan to an Exhaust Fan to help pull unwanted moisture out of the crawl space. The Portable fan is connected to a 10" - 2ply - double walled - flex duct and to a 8"x16" foundation air vent to newly designed duct connectors. Evacuating air from the crawl space removing radon, odors and moisture from under the house.
What is CFM?
CFM means Cubic Feet per Minute. CFM helps determine what size fan will suit your crawl space ventilation needs. When purchasing a fan you want to know how much air the fan will move. Air movement is measured in CFM. To calculate the volume of air in the crawl space you multiple the height x width x length of the crawl space. For example, if your crawl space is 40' long, 20' wide and 3' high the volume on air in the crawl space is 2,400 (40x20x3) cubic feet. If you want to replace all of the air in this crawl space every 4 minutes you need a 600 (2,400/600) CFM fan.
What is the benefit of using a Fan Control System?
A fan control system has various components, including humidistats (instruments for measuring and controlling humidity) and a thermostat. The fan control system turns the fan on and off. The fans can be controlled to come on when the crawl space humidity reaches a certain preset amount. Similarly, they can be set to not come on if humidity is higher outside the crawl space than inside the crawl space, or when the temperature in the crawl space is cold enough to freeze pipes.
When I am finished using the portable fan exhaust system, what other uses can the various parts provide me?
The portable fan can continued to be used to move "dead air" in the crawl space.
The 8"x16" manual air vent can still be used to ventilate the crawl space, providing 95 NFA-double most air vents on the market.
